There is a product on the market called pearlie!you paint it on and it last till you next brush your teeth,
It's ok but it does look like you've applied tip ex!
I did try this about a year ago but it also feels awful on your teeth,Best product that realy deos work
Is used by dentists and costs a fortune,it is a 22% peroxide gel,which you can get from ebay!its better to get it from America, its alot cheaper even with postage!make sure you get 22% though as any lower will take longer to work,
If your anything like me i want it to work instantly!!and it does ,you can tell immediatly,it takes about 1 week to 10 days for to go white!,Just press teeth whitening on ebay and you should find some!
